If you can find somebody that will do it for you, you'll still need the SID to link to your computer for the myReef 2.0 software. If you go to the DA site you can buy one through them.

If I was you though, I'd take the original SID that came with your RK and send it to them to update it. I wish that I had done that instead of buying one. The old style is way better and has a much longer cord on it. This is a free update from them. I may end up doing this, and I salready bought the new style... out of lazyness.
